Filed March 9,A 1931 Patented Aug. 9, 1932 STATES HENDRIK NOLET, OFARNHEM, NETHERLANDS, ASSIGNOR TO ALGEMEENE KUNSTZIJ DE I UNIE N. V., FARNHEM, NETHERLANDS Y APPARATUS FOR TREATING CHEESES WITH LIQUIDSApplication filed March 9, 1931, Serial No. 521,331, and in theNetherlands February 18, 1930.

|Ihis invention relates to a process for treating crosswound bobbins orcheeses, more particularly of articial silk, with'liquids. By means ofthe invention artificial silk may be produced forthwith in a wound formsuch as is usual in commerce, and in this wound form may be subjected tothe various after-treatments. v

The purpose of the invention consists in the fact that the artificialsilk is washed, bleached, desulphurized, and if necessary dyed withoutit being necessary previously to re-spool or reel the product. In-thisway a very considerable saving of work is proi duced. Furthermore, thedanger of damaging the yarn is considerably diminished, if noteliminated altogether.

According to this invention the cheeses are arranged with the aid ofintermediate members, in a tube, which may be divided into longitudinaldirection, and are there subjected to the various liquid treatments. Y

According to the invention intermediate members may be used, which maybe provided with perforated tubular portions or flanges which proj ectwholly orpartially into the central opening of the cheeses.

Further, according to the invention, the liquid may be forced or drawnthrough the cheeses either from the inside to the outside, or viceversa, or alternately from the inside to the outside and from theoutside to the inside.

'Ihe process according to the invention may also be carried out in sucha Way that the cheeses are immersed partially or wholly in the liquidand rota-ted about their longitudinal axes.

Finally, the invention embraces a modificatiton in which the cheeses arejacketed with a permeable fabric before the treatment with liquid takesplace.

For the purpose of elucidating the inven- Y tion a detailed descriptionof the new process is herewith appended, said description referring tothe accompanying drawing in which one of the many modifications of theinvention is given as an example.

In the accompanying drawing l, l, 1 are the cheeses which, for example,are spun on .a

suitable permeable layer 2, e. g. of cotton. l

The various spools are arranged in the tube 3 which is provided withperforations 4. In order to facilitate the introduction of the cheesesinto the tube, the latter may consist, for example, of two parts dividedalong an axial, vertical plane as at 8, forming edges which fit on toone another in a longitudinal direction and may be secured to one antherin any suitable manner. The securing means have here been shown as anannular cap 9 tting over the top, and a cup-shaped base 10 closing thebottom end of the tube 3. The cap and the base may be threaded on theends of the tube or only pushedon tightly. Suitable intermediate membersare arranged between the cheesesl, l which, according totheconstructional example shown, are provided with tubularprojections 6which project into the cheeses; rThe intermediate Vmembers 5 are'provided with a central opening through which the liquid can flow. Ifnecessary means may be provided to maintain the intremediate members 5at definite distances from one another.`

After the introduction ofthe cheeses into the perforated tube 8, thehalves of the tube are well secured to one another, whereby the `cheesesaresomewhat pressed together in frombelow, the tube being closed at thetop" in the form of cheeses at the start does notfr 7 any longer have tobe unwound, reeled or subjected to similar operations. i f

The employment of the process according to this invention, therefore,notonly implies a considerable protection of the artiicial silk during thetreatment With liquid Y but it also involves a substantial saving incosts. 1

vWhat I claim is:

or cheeses, consisting of a tube split into tvvo parts longitudinally,intermediate pieces having a central bore and perforated tubularprojections on these intermediate pieces, the height of which is lessthan half the height of the coils or cheeses.

v9. An apparatus for Washing cross coils or cheeses, consisting of aperforated tube ydivided in the longitudinal direction, intermediatepieces having a central bore, which are provided on both sides Withperforated tubularprojections, a pervious layer inside the coil and anon-perforated connecting oue arranged at the end of the perforated tue.

In testimony whereofI I have signed my name to this specifica-tion. Y Y

l. An apparatus for Washing cross/coils Y or cheeses, consisting of aperforated tube, the `inner diameter of which corresponds roughly to theouter diameter of the coils, and intermediate pieces With a centralbore,

which are inserted between lthe end faces of the coils.

2. An apparatus for Washing cross coils vor cheeses, consisting of aperforated tube,

the inner diameterof Which"roughlyv corresponds to the outer diameter ofthecoils, and intermediate pieces having la centralk bore, which areinserted between the end faces of the coils, and means, which arevadapted, to pass the treating fluids through the coils and through thewall of the perfo# rated tube. j .v

3, An' apparatus forwashinfr cross coils or cheeses, consistingV ofa'perforated tube divided in the longitudinal direction, intermediatepieces having a central bore and Y tubular projections on the same, thediameter of which roughly corresponds tothe diameter of the interior ofthe coils.

a. An apparatus as claimed in vclaim 1, in which the perforated tube isclosed 'at one endA and provided at the other end With an aperture. Y

5. An apparatus for Washing cross coils or cheeses, consisting of aperforated tube closed at one end and a non-perforated connection tubelocated att-he other end of the tube, Which connection tube is suitablefori connecting the interior of the tube with a suction device. j

6. VAn apparatus as claimed in claim 3, in which the tubular projectionslocated on the intermediate pieces are perforated.

7. An apparatusfas claimed in claim`3, in which the height of thetubular projections, arranged on the intermediate pieces is less thanthe half height of the coils placedv thereon.
